Full title and description

ISO 20054:2022 — Plain bearings — Bearings containing dispersed solid lubricants. This international standard specifies characteristics, materials, dimensions, assembly and surface finish for plain (solid-lubricant) bearings that contain dispersed solid lubricants and are intended for applications where self‑lubrication is required.

Abstract

This document specifies the characteristics, materials, dimensions, assembly and surface finish for a bearing containing dispersed solid lubricants which is used as a solid lubricant bearing. It clarifies the dispersed type among the solid-lubricant bearing family (solid, coated, embedded and dispersed types) and gives requirements to support design, manufacture and acceptance of these plain bearings.

Scope

ISO 20054:2022 applies to plain bearings that incorporate dispersed solid lubricants. It sets out requirements for the bearing’s defining characteristics (materials and composition), dimensional data and tolerances, recommended assembly practice and surface finish criteria necessary to ensure reliable self‑lubricating performance in service. The standard is focused on the dispersed‑type solid lubricant bearing within the family of self‑lubricating plain bearings.

Key topics and requirements

• Definitions and classification of solid‑lubricant plain bearings (solid, coated, embedded, dispersed).
• Material and composition requirements for bearing matrix and dispersed solid lubricants.
• Dimensional specifications and tolerance tables for common bearing forms and bushings.
• Surface finish requirements and recommendations to optimise lubricant release and run‑in behavior.
• Assembly and installation guidance to avoid damage and ensure proper seating.
• Marking and identification details for manufactured bearings.

Typical use and users

Typical use cases include rotational, reciprocating and oscillating motions, frequent start/stop conditions and low‑speed/high‑load applications where fluid lubrication is impractical or undesirable (for example vacuum, clean-room, medical devices, aerospace subassemblies, robotics and many industrial mechanisms). Primary users are bearing and bush manufacturers, mechanical design engineers, OEMs, procurement and quality teams specifying or validating self‑lubricating plain bearings.

Related standards

ISO 20054:2022 is part of the plain‑bearing family of ISO standards. Related publications commonly referenced when specifying or selecting plain bearings include (non‑exhaustive): ISO 2795 (sintered bushes), ISO 3547 (wrapped/rolled bushes), ISO 4379 (copper‑alloy plain bearings), and the ISO 12240 series (spherical plain bearings). It formally replaces ISO 20054:2016.

FAQ

Q: What is this standard?

A: ISO 20054:2022 is an international standard that specifies requirements for plain bearings that contain dispersed solid lubricants (a type of self‑lubricating plain bearing), covering material, dimensional and surface‑finish criteria and assembly guidance.

Q: What does it cover?

A: It covers the characteristics, acceptable materials and compositions, dimensional specifications and tolerances, assembly recommendations and surface finish requirements specific to dispersed solid‑lubricant plain bearings to ensure proper performance in service.

Q: Who typically uses it?

A: Bearing manufacturers and material suppliers, mechanical design engineers and OEMs, procurement and QA/test teams — essentially anyone specifying, producing or validating self‑lubricating plain bearings for industrial, aerospace, medical, vacuum or robotics applications.

Q: Is it current or superseded?

A: ISO 20054:2022 is the current published edition (Edition 2, published 24 June 2022) and replaces ISO 20054:2016. Users should confirm whether their national adoption or a related national standard introduces additional front matter or national forewords.
